Given its a parent situation, and by you saying "landlord" and not just calling him the landlord, this makes me wonder if you have an actual lease and are infact legally a renter. A legal renter protected by the document would need to go through the legal eviction process. A kid/adult living with their mom and step-dad (even if you pay them rent every month) who may have over stayed their welcome ( in the eyes of the parents) and are not a minor, then yes of course they can simply be kicked to the curb. No different them if they were a trespasser. And without a proper lease, if you refuse to leave, they can even call the cops and force the issue Note this is not my legal opinion and would be the same in florida too. This is simply common sens/fairly standard laws. Unless you live in some very left leaning jurisdictions that actually protect squatters, it all hinges on what legal documents and proof you have the gives you the right to be there.
